PPLICATION
The BC series is the standard line of
high density IEC/DIN rail-mounted
terminal blocks. BC series terminal
blocks vary in thickness, but only
three profiles achieve the ultimate in
ergonomic design. Certain models
are available in a non-jumperable
version at considerable cost savings
to the user.
